Transcript
"To my good friend and Fatebinder,

Hastily, I find myself writing (under pain of death and dismemberment) on behalf of one sir 'Octave of the Scarlet Chorus' who wishes to succinctly inform you, and I quote:

"Boss, my gal Pustule tracked Rending-Hound through Stone Down, but the mutt nearly gored her throat out then fled east, toward Howling Rock. I'd bet my last ring, he's holed up near Cairn's remains."

Always happy to be of service... even when my services, it seems, must go unpaid...

- Sage Monophthong, on behalf of Octave"
